Welcome to the forum. Looks like a very nice clean rig. If the shutter needs service I'd recommend sending it to Flutot's in S. Cal; Carol is very good and a pleasure to deal with. Although she sometimes has a backlog of work and may have longer turnaround times. IIRC she has noted on her website that parts for Compur shutters are becoming hard to find, but if it only needs cleaning there should be no problem.

The camera appears to have a non-Sinar fresnel, rather than the easily detachable 4x5 Sinar version (which is a plastic one and is easily scratched by a loupe). So it may be a glass version as a replacement, but you should check it with a loupe to make sure its focal length performs properly with your lens.
Often the bubble levels run dry, and replacements can be a challenge; but a search of this forum will turn up methods to repair/refill yourself. Although, all my Sinar Normas, bought new in the '70s, still have full levels. MOST Sinar parts are interchangeable with other models. Here's one of their useful websites:

Enjoy your camera,
